Key Exchange Algorithms

ecdh-sha2-nistp256
Elliptic Curve Diffie-Hellman on NIST P-256 curve with SHA-256 hash
Possible NSA backdoor. 		Secure
diffie-hellman-group14-sha1
Diffie-Hellman with 2048-bit Oakley Group 14 with SHA-1 hash
Oakley Group 14 should be secure for now. SHA-1 is becoming obsolete, consider using SHA-256 version. 		Weak
diffie-hellman-group1-sha1
Diffie-Hellman with 1024-bit Oakley Group 2 (not a typo - see RFC) with SHA-1 hash
Oakley Group 2 is no longer considered secure. 1024-bit groups may be broken by nation states. 		Insecure

Server Host Key Algorithms

ecdsa-sha2-nistp256
Elliptic Curve Digital Signature Algorithm (ECDSA) on NIST P-256 curve with SHA-256 hash
Possible NSA backdoor. 		Secure
ssh-rsa
RSA with SHA-1 hash
SHA-1 is becoming obsolete. 		Secure

Encryption Algorithms

des-cbc-ssh1
Unknown
aes256-ctr
AES with 256-bit key in CTR mode
Secure
aes192-ctr
AES with 192-bit key in CTR mode
Secure
aes128-ctr
AES with 128-bit key in CTR mode
Secure
aes256-cbc
AES with 256-bit key in CBC mode
CBC mode is not perfect, but still not "unsafe". 		Secure
aes192-cbc
AES with 192-bit key in CBC mode
CBC mode is not perfect, but still not "unsafe". 		Secure
aes128-cbc
AES with 128-bit key in CBC mode
CBC mode is not perfect, but still not "unsafe". 		Secure
blowfish-cbc
Blowfish with 128-bit key in CBC mode
At least 128-bit block size is recommended; Blowfish uses 64-bit blocks. CBC mode is not perfect, but still not "unsafe". 		Weak
3des-cbc
TripleDES with 192-bit key (112-bit effective security) in CBC mode
3DES is very inefficient. 		Weak

MAC Algorithms

hmac-sha2-256
Hash-based MAC using SHA-256
Secure
hmac-sha2-512
Hash-based MAC using SHA-512
Secure
hmac-sha1
Hash-based MAC using SHA-1
SHA-1 is becoming deprecated - consider replacing with SHA-256 or SHA-512. 		Weak

Compression Algorithms

none
No compression
Unknown
zlib
zlib compression
Unknown
zlib@openssh.com
zlib compression by OpenSSH
Unknown
